@Dazais wh*** so basically MC's cousin's (forgot the name) father reported to the king about the MC's parents collecting the evidences about the murder of the king's wife who was a princess of another kingdom which lead to MC's parents dead. And form the previous chapter we know that MC's parents were killed by the queen but if the cousin's father hadn't reported about what was MC's parents were doing than they wouldn't have died so cousin's father was basically the reason why MC's parents had died.
@Dazais wh*** oh I forgot to tell you the queen killed the King's wife with help of poison master kafir if found out it would have lead to war so king was trying to hide it by killing kafir and ordered cousin's father to kill kafir but kafir was alive and MC's parents found out
